Answer:

Explanation:
As given
Sean Pinsky’s checking account had a balance of $137.66. 
Sean Pinsky’s wrote a check for $23.62 on September 3.
 On September 7, the bank made an automatic transfer (AT) of $25.41 to pay his phone bill. 
Sean Pinsky’s made a deposit of $146.24 on September 12. 
New balance in Sean's account = Account balance - Check amount - Phone bill + Deposit amount 
Put all the values in the above 
New balance in Sean's account = $137.66 - $23.62 - $ 25.41 + $146.24 
 = $234.87 
Therefore the new balance in Sean’s account is $234.87 .
